Check Digit Verification of cas no

The CAS Registry Mumber 137623-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,2 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137623-33:
(8*1)+(7*3)+(6*7)+(5*6)+(4*2)+(3*3)+(2*3)+(1*3)=127
127 % 10 = 7
So 137623-33-7 is a valid CAS Registry Number.
